# DecisionRules Server

{% hint style="success" %}
Production Container
{% endhint %}

Download the latest [DecisionRules server container](https://hub.docker.com/r/decisionrules/server) that provides all the backend functionalities with maintenance and regular updates. The server requires [Redis Cache](https://redis.io/) and [MongoDB](https://www.mongodb.com/).

## Container types

{% hint style="info" %}
Since version 1.15.0 the container runs with a non-root user
{% endhint %}

## How to start the Decision Rules server

The server can only be started with the set of env. variables that are necessary for operation.

### Method 1: Pulling and running the Docker container in the terminal

The server can be started using a simple `docker run` command. If you don't have the container downloaded yet, you can pull it using the docker pull command.

```
//pull container
docker pull decisionrules/server
//run container alone
docker run -d -p 8080:8080 -p 8081:8081
-e WORKERS_NUMBER=1
-e REDIS_URL=YOUR_REDIS_URL
-e MONGO_DB_URI=YOUR_MONGODB_URL
-e CLIENT_URL=http://localhost:80/#/
-e LICENSE_KEY=YOUR_LICENSE_KEY
-v license:/assets/lic/ decisionrules/server
```

{% hint style="info" %}
Some env. variables can be omitted. For full list of env. variables see [here](/doc/v1/on-premise-docker/containers-environmental-variables.md).
{% endhint %}

### Method 2: Creating your own docker-compose file

If you don't want to use too much terminal you can create your own docker-compose file. The file type is YAML.

```yaml
version: "1.0"

services:
    server:
        image: decisionrules/server
        environment:
            - "REDIS_URL=YOUR_REDIS_URL"
            - "MONGO_DB_URI=YOUR_MONGO_URI"
            - "CLIENT_URL=YOUR_CLIENT_URL"
            - "LICENSE_KEY=YOUR_LICENSE_KEY"
        ports:
            - "8080:8080"
            - "8081:8081"
        volumes:
            - license:/assets/lic/:rw
volumes:
    license:
        driver: local
```

{% hint style="info" %}
Docker compose files are started with `docker compose up` command.
{% endhint %}

#### What not to forget

* The server must be accessible from your browser for the client app to work.
  * You can easily check your connectivity [SERVER\_URL/health-check](https://api.decisionrules.io/health-check) - you should get HTTP 200 OK Response

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.decisionrules.io/doc/v1/on-premise-docker/decisionrules-application/server-app.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
